Is it even or odd ......

My special number is even because it is divisible by 2 I know because I was doing the factor rainbow and if I did the factor ranbow of 30 than it will chos me that 2 is multipled by 15 to make the numer 30.For example the number 20 is even because it's dyvysebel by 2 and 60,80,40,100,and50.ther's much more but it will take me hours to do each one I can think of.Numbers like 90, 11,12,13,15,and 70 those numbers are not even those numbers are called odd numers those are numbers that are not divisible by 2.
